The city’s war on rats is missing a key element — a body count.

The boxes will trap the rats that go for the bait, allowing the city to track how many get poisoned.

For years, Halstead Property’s Richard Grossman has run a boot camp, teaching agents how to get buyers approved by co-op boards. In it, he presents four hypothetical applicant profiles. The first is a professional — a teacher, perhaps — with an average income but an outsize down payment. The second is a bonus-dependent candidate like a banker, who makes $80,000 and is putting down the minimum, but has a bonus three times his salary. The third, a non–Wall Streeter, earns somewhere in the low six figures and has a small bonus and a standard down payment, and the fourth, a first-time buyer with a good job, relies on relatives to cobble together a decent down payment.

In the past, says Grossman, agents invariably picked the financier as the most board-worthy, thanks to his bonus. At last month’s seminar, however, the answers were unanimous: “Go with the teacher.” And that is a big change. “If you were bidding against someone from Wall Street who had this kind of bonus history, you couldn’t compete. First of all, they were willing to outbid you, and second of all, the sellers were willing to take them over somebody else,” says Gumley Haft Kleier president Michele Kleier. “Bonus used to be the favorite word in everybody’s vocabulary. Now salary is a much more attractive word.” Admits one Upper West Side board member: “We’re definitely cautious across the board now, especially when someone’s touting their bonus.”

The Manhattan madam linked to former Gov. Eliot Spitzer claims she had a “connection” and “flirtation” with scandal-scarred Yankees slugger Alex Rodriguez.

When asked if the Yankee patronized her escort agency, Davis, who said she likes Latin men, would only say that they had a “professional” relationship.

A riot erupted at a Brooklyn restaurant last week when Orthodox Jewish patrons discovered the “kosher” hot dogs on the menu were chicken franks that didn’t answer to a higher authority.

Suspicious, he asked for proof of where the hot dogs were bought. The server brought him the package, which confirmed the Bar S brand jumbo chicken frank was not certified kosher.

Congress’ planned 90 percent tax on bonuses paid by bailed-out companies will snatch $12 billion at the very least from employees of firms that are based in New York City or have big operations here, experts said.

For example, he said, at least 50 percent of the $2.6 billion that Goldman Sachs gave its employees in bonuses would likely be hit with the tax.
